RECEIVER OF HEEL-NAILING MACHINES.

Patented Feb. 12, 1918.

To all whom it may concern:

Be it known that I, \VILLIAM E. SCARLETT, a citizen of the United States, and resident of East Lynn, county of Essex, Commonwealth of Massachusetts, have invented an Improvement in Receivers of Heel-Nailing Machines, of which the following descrip tion, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts in each of the several views.

This invention relates to receivers of power heel nailing machines, of a type adapted to receive and position the heel portion of the shoe in correct alinement for the nailing operation. One prime object of the invention is to provide improved means adapted to yield vertically to a limited ex tent with the vertical movement of the heel after it is pressed thereagainst and as it is forced up against the nailing plate to be held secure for the nailing. A further object is to prove an improved construction of flaring guide cheeks adapted to receive and aline the heel portion part of the shoe, by engaging the same farther back than usual so that the alinement is more nearly uniform for rights and lefts than has heretofore been the case. A still further object is to provide an improved mounting of the lateral guides with improved adjusting means therefor. The above and other objects and features of the invention will be better understood from the following detailed description taken in connection with the accompanying drawings and will be thereafter pointed out in the appended claims.

Referring to the drawings:

Figure 1 is a front view of a receiver constructed in accordance with my invention;

Fig. 2 is a side view thereof;

Fig. 3 is a plan view; and

Fig. 4 is an enlarged sectional detail on line l4t of Fig. 1.

The body of my improved device consists in an upright block or slalo 10 adapted to be fixed to the frame work of the machine. At the top of the body are upstanding pins 11 to which is slidably fitted a bracket piece or block 12 which is normally held up to its upper limit of movement against cotter pins 13 at the top of the pins 11 by a spring 14 housed in recesses of the body 10 and the block 12 and reacting against said block. The top of block 12 is formed as a backing guide for the upper heel portion of the shoe as seen at 15. The top of this backing portion is recessed as seen at 16 to receive a block 17 which is clamped therein, the backing 15 being for this purpose split vertically and its two sides drawn together by a screw bolt 18. The block 17 has an upstanding lug 19 formed with a pivot bearing 20 for a heel gage formed as a plate or block 21 with its front formed as a wide V 22 to receive the heel and gage the position of the same. This heel gage is beveled off back of its pivot as seen at 23 so that it may tilt upward to some little extent, it being normally, however, held yieldingly pressed downward against the block 17 by a spring 24 housed in and reacting between these members. It may now be understood that with the described construction as the shoe on the last is set in place on the jack post with the heel upper against the backing 15 and the heel lift set in gaged position against the gage piece 21, as the jack post is moved up manually to clamp the heel on to the shoe against the nailing plate above, the lifts of the heel will be pressed up some little distance by this preliminary clamping pressure and the rough unfinished exterior thereof will tend to catch on the gage 21. By reason of the yielding tilting mounting of this gage, however, no harm results from this, the gage merely swinging up with the heel to the extent required in this first clamping compression. Thereupon as the power head descends, the heel lift and also the upper heel portion of the shoe will be crowded down somewhat by the heavier final clamping pressure as exerted upon the nailing plate from above by the power head. This downward movement of the shoe is taken care of by the yielding of the spring 1 1 which permits the backing block 12 carrying with it the gage 21 to move easily down ward with the shoe as much as it goes under the compressing action of the power head.

The lateral guide plates for alining the heel transversely are indicated at 25 mounted on vertical pivots 26 on the tops of arms 27 pivoted at 28 at the sides of the bottom of the body 10. The arms 27 are adjustable simultaneously toward and from each other by a rod 29 with right and left hand threads at its respective ends engageable with swivel nuts 30 in said arms, the bolt being ournaled in the body and held against movement lengthwise by having a sleeve 31 fixed thereon fitted in a recess 32 of the body. A suitable operating head shown as a knurled disk 33 is fixed at the end of the rod 29. The guides 25 extend as bell crank levers back from their pivots 26 as seen at 3% in approximate parallelism with horizontal projections 35' at the tops of the arms 27. The ends of the extensions 34 are yieldingly drawn toward the projections 35 so as to swing the guides inward by tension springs 36 fixed to and reacting between these parts and the extent to which the guides may be thus moved inward is limited by step pins 37 threaded through the projections and acting against the arms .34; thus providing means whereby the normal position of the guides may be individually varied and determined as required for different kinds of work. I consider this vertical pivoting of the guides 25 for individual adjustment in conjunction with the mounting thereof on the relatively long vertical arm 27 for swinging on the horizontal axis 28 to be a valuable feature of invention since thereby the plates are kept in substantia ly, the same vertical relation and free from canting angular displacement to the shoe throughout their range of adj ustment; this for the reason that the main simultaneous adjustment effected by the screw rod 29 is about the relatively distant pivots 28 so that no appreciable canting or angular displacement of the guide plates results, while the individual adjustment of the guide plates at the top of arms 27 about the vertical pivots 26, of course does not produce any angular displacement at all trans versely of the shoe. In accordance with my invention the guide plates 25 flare outward somewhat from the backing gage 21 as best shown in Fig. 3 in their normal inward position. The purpose of this is to enable the requisite hold to be obtained on the heel. portion of the shoe farther back than would be the case were said guide plates substantially parallel as is usual. This is advantageous in that it makes the positioning of the shoes more nearly uniform and substantially the same for rights and left s, it being understood that the farther toward the front the point of engagement is made, the more of a difference there is in the lateral positioning of lofts and rights, since when the guide plates are far enough front to engage the exces'scheek or bulge at the outer side of the shoe, it of course presses the shoe over correspondingly. The aim of the present outwardly inclined guide plates is to provide a form of holder and guide that will catch the sides of the rear portion of the last so as to retain the shoe and yet be far enoughback to miss the variation in the cheek or bulge of the shoe that begins some little distance from the back of the heel. It is to be understood that the several features of the invention set forth may be used in other relations and embodied in other specific forms without departing from the spirit of the invention and I therefore desire the present embodiment. to be considered as illustrative and: not restrictive referring rather to the appended claims to indicate the scope of the invention.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A receiver for heel nailing machines,

comprising a backing gage mounted for limited yielding movement upwardly from a normal position, a mounting for said gage constituting a rest for the back of a last and fitted to yield downwardly, and last positioning means associated therewith.

2. A receiver for heel nailing machines, comprising a backing gage mounted for limited yielding movement upwardly from a normal position, a mounting for said gage constituting a rest for the back of the lastand fitted to yield downwardly,v and yielding means for positioning the last laterally.

. 3. A receiver for heel nailing machines, comprising a backing gage to position the last and heel endwise, and means for engaging the sides of the last to retain the shoe, said means consisting in a pair of plates presenting approximately plane faces nor? mally flaring outward to engage the back of the last far enough to the rear to miss the variation in cheek 0r bulge therein.

t. A receiver for heel nailing machines,.. having opposite members mounted. to swing horizontally, for engaging. the backof' the last laterally, the mountings of said members being pivoted to swing in vertical pl ane-s on relatively remote axes, means for simultaneously adjusting said mountings, means for yieldingly drawing said members together, and means for individually limiting the inward movement of the respective members. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
